Abstract
PURPOSE: To expand a low frequency band characteristic by a small-sized speaker box by freely varying the cavity resonance frequencies of first and second ports provided on the one surface and the back plate of the speaker box or sound volume, emitted through these two ports.
CONSTITUTION: The sound pressure frequency characteristic (e) of a speaker system is obtained by synthesizing frequency characteristics e1 and e2, obtained by a cavity resonance between the first port 5 and the second port 6, provided on the back plate, and the low frequency band characteristic can be widely expanded compared with the sound pressure frequency characteristic (a) of the tightly closed box of the same volume. In case of the speaker system is installed in a listening room, and is evaluated in an audition state, because it is installed at the corner or the vicinity of the wall of the room, it is auditioned as the composite sound of the sound (f) emitted from the front face of the speaker system, and the sound (g) emitted from the port 6, provided on the back plate. The sound (g) is expanded at its low frequency by the wall 11 and a floor, and the sense of low frequency of the sound pressure frequency characteristic is expanded, compared with an anechoic room.
